A hydraulic device, such as a motor or pump, includes a first set of components (1C), which includes a housing member, and a second set of components (1D) secured to the first assembly. The first and second components are respectively provided with a first contact and a second contact surface (1C ', 1D'), the two contact surface with the applied axial pressure device (15) is towards each other and are in contact with each other for extrusion. At least one of the first contact surface and the second contact surface has a rough friction surface. With the surface, high torque can be transmitted between the first and second sets of components. The invention also relates to a method for manufacturing the same.
